Here is a small, quick port of the latest version of vgmplayer, which can play TONS of Arcade and classic game tunes!
The GUI supports preview pictures for the games as well.
You can grab it from the Repo.
And most important: Grab the Videogametracks from here: http://vgmrips.net/forum/viewtopic.php?f=1&t=496
Simply unzip the full pack somewhere you want and enjoy the music.
If you don't want the full pack but download single packs, grab them here: http://vgmrips.net/forum/index.php
No need to unzip the single packages.
Enjoy
